[Abstract]:With the rapid development of science and technology and economy, people's living standards are constantly improving. People begin to pursue a more comfortable, convenient and safe life. The emergence of smart home meets this requirement. As one of the core technologies of smart home, video surveillance technology makes people's personal and property security better. However, the traditional monitoring system has always been inflexible, inefficient, high maintenance costs, and can not be well applied to the popular smart home products. Therefore, the market urgently needs a flexible, stable performance, low maintenance costs, active analysis and early warning of the video monitoring system, intelligent video monitoring system. Intelligent video surveillance system has attracted more and more attention from the market demand. The demand for intelligent video surveillance system is increasing. From the technical point of view, intelligent video surveillance system will adapt to more complex and changeable scenes and analyze and identify more abnormal behaviors. Intelligent video surveillance technology is a forward-looking scientific research field, not only contains huge scientific research value, but also contains huge commercial value. In the aspect of intelligent mobile terminal, the Android platform developed by Google has greatly promoted the development of intelligent mobile terminal, because of its open source, it is based on Intelligent hand. At present, Android system has a large market share in the smart mobile terminal market, and also occupies an important position in people's lives. Therefore, the design and development of an intelligent video surveillance system based on Android platform has practical significance and practical value. The main contents of this paper include the overall plan and design of the intelligent video surveillance system based on Android, the design and implementation of the system software, and the test of the system under different network application environment. The system adopts C/S design pattern, and divides the system into two parts: server and client. The development and debugging of the server software use Visual S. Tudio 2012 software, client software is developed using Eclipse software and debugged using Android virtual machine. Server mainly realizes video capture, video coding, streaming media transmission, intelligent processing and network transmission, modular design of the server software, video capture module using OpenCV open source library camera interface function, through. Video encoding module implements H.264 encoding, and uses H.264 encoder in X.264 open source library to encode YUV color space video source; Streaming media transmission module completes RTP/RTCP protocol packet and transmission of H.264 encoded video stream; Intelligent processing module uses OpenCV open source library. The client software also designs and implements each module. The client is divided into UI interface module, video receiving module, video decoding module, video playing module and network transmission module. UI interface module uses various components provided by Android SDK to design, display and interact with users; Video receiving module uses C language to write RTP packet parsing and unpacking program, and then uses JNI technology to call the program in JAVA program to achieve video reception; Video decoding module uses Androi to achieve video reception. D NDK transplants FFmpeg open source library to realize H.264 decoding in Android system; video playback module uses Android SDK's surfaceview component to lock Canvas canvas to surfaceview component and draw pictures frame by frame on the canvas to realize video playback; network transmission module uses socket network programming to realize socket with server side. Finally, the server software and client software are debugged and tested jointly. The network application environment tested uses the campus network WiFi and the 4G (TD-LTE) network in the laboratory environment. The test results show that the function and performance of the system have reached the expected design under the network environment. Through the above work, the system is successfully implemented based on the above work. Android platform intelligent video surveillance system development, after the test system runs stable, clear screen, delay within the control range. The system gets rid of the traditional video surveillance needs personnel on duty, 24 hours a day intelligent surveillance, when the detection of suspicious targets promptly notify users to view video surveillance. Frequency data is not stored, so the pressure of video storage is greatly reduced. Users do not need to pay extra labor costs and video storage space costs. The intelligent video surveillance system based on Android has the characteristics of strong network adaptability, low installation and maintenance costs, stable system operation, and can be used in smart home. The application of intelligent video surveillance provides a design idea and solution.
